The question is how best to setup effectively the Sonos:playbase, amp, and port. The setting: a Motorola amp, Sony CD player, Sony DVD player, dual casette tape player, Panasonic TV, and independent turntable. I also have the playbase with four Sonos speakers currently in surround sound with the Panasonic. Finally, with a small LG TV I have a two Sonos speakers, and a beam set up in stereo. There are 4 additional speakers, three of the one variety and 1 sonos3. I am attempting to put the best subsystems together regardless of what entertainment unit I use. So, what would be your suggestions, please. Feel unconstrained on all the Sonos system as I am trying to get to the most effective sub-systems.
